High country winter scene. Bristlecone pine tree snag (Pinus aristata) at the Windy Ridge Bristlecone Pine Scenic Area near Alma, Colorado. Ancient bare tree in snowy meadow with a forest of conifer trees behind it in the middle ground. The snag is casting a shadow on the snow in the foreground. Snow covered mountains in the distance on the horizon. Blue sky significantly obscured by a thin veil of white cloud cover.

Woodland forest scene. Park bench in foreground located next to a dirt walking path which winds from the lower right of the frame diagonally toward a curve in the middle left. The forest floor across the foreground and middle ground is covered in leaf litter, with several patches where the blades of grass and spring flowers are beginning to appear. The forest is filled with deciduous trees, most of which are bare and leafless, with a few trees beginning to faintly show spring leaves.  The Morton Arboretum, Lisle, Illinois.

Biking today 🚲, stopped at Genesee to check out the buffalo. This one was chill - walked up, laid on the ground near where I was standing, and heaved a deep sigh. Added a stop at Wildcat Point, and when I got home discovered my youngest had baked gingerbread banana bread muffins while I was out.
